Police have arrested a 25-year-old man accused of robbing a pregnant woman of her purse at gunpoint in a northwest Dallas parking lot earlier this year.

Ignacio Gallo faces an aggravated robbery charge in the attack on the 32-year-old woman reported on April 7 in the 10700 block of Composite Drive near Walnut Hill Lane, according to police documents.

The woman told police she was making a u-turn to exit the parking lot after she realized a nearby business was closed. One of two men in a dark green minivan waved her down and asked her for directions about 8:40 p.m., she said.

As she spoke to the man, another man emerged from the van and quickly approached. He pointed a dark colored handgun at her forehead, police said.

"Gimme your wallet and phone and stop screaming or I'm gonna kill you," the gunman, believed to be Gallo, said.

As the woman screamed, police believe Gallo tried to open her door and broke off the handle. The woman was eventually able to escape and ran onto Composite Drive shouting for help, the documents said.

She called 911 and authorities who responded lifted fingerprints from the interior of the driver's side front window. Ten days later, the prints were matched to Gallo, police said.

Earlier this week, the victim was shown a six-photo lineup and identified Gallo as the man who robbed her.

Gallo is being held at the Dallas County Jail, where his bail is set at $100,000. He is also suspected of being in the country illegally, according to jail records.
